In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.

I have read and understood the above.

Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

Description

ABSTRACT

Conventional solar cells based on Si are still expensive; their production requires high temperature and a large amount of energy, causing environmental concerns for their extensive application to solve the global energy crisis.
The discovery of fullerene [1] and conducting polymers at the end of last century[2], opened a new avenue, offering the possibility to create solar cells by using simple and environmentally friendly chemical processes.
Solar cells based on polymer-fullerene mixtures (bulk-heterojunction) recently achieved more than 8% efficiency, sparking enthusiasm all over the world, but several hurdles still limit a widespread application of this technology.
In this seminar I will introduce the basic concepts of the bulk heterojunction and I will present the results recently obtained by our group [3-5] in the microscopic investigation of polymer wrapping on carbon nanotubes, which suggest the way to improve the efficiency of these devices.
